High Temperature Alarm Circuits
This series of high temperature, serves to warn us about the increase in temperature, a temperature sensor which is used thermistor (TH1), the normal temperature of approximately 25 ° C the resistance of the thermistor approximately 10 K and at increased temperature reaches 94 ° C thermistor will resistant to change until they reach of about 1 K, the existence of this value changes that would enable Darlington Q1 and Q2 to drive the relay which is connected to the alarm. Power supply 9 VDC using the voltage, this circuit can be used to control the fire. Read entire Article »
